Figure 1

An example of an (a) original polar map JPEG image before cropping and resizing to smaller dimensions. After cropping and resizing, (b) only the polar map and the superimposed regional markings signifying LAD, LCX and RCA remain in a rectangular shape of 256 × 256 pixels. All polar maps were scaled between 0 and 3.5 ml/g/min before image export, where red and yellow color indicate normal stress MBF, whereas green and blue color indicate reduced stress MBF.
